What should come in place of ? in the given series based on the English alphabetical order?
TLP SKO RJN QIM ?

The correct option is PHL.

To find the missing term in the series TLP, SKO, RJN, QIM, ?, let us analyze the pattern followed by each letter position across the terms in English alphabetical order.

1. First letter pattern:
T → S → R → Q → ?
- T has positional value 20
- S has positional value 19 (20 - 1 = 19)
- R has positional value 18 (19 - 1 = 18)
- Q has positional value 17 (18 - 1 = 17)
Following the pattern of decreasing by 1, the next letter is 17 - 1 = 16, which corresponds to P.

2. Second letter pattern:
L → K → J → I → ?
- L has positional value 12
- K has positional value 11 (12 - 1 = 11)
- J has positional value 10 (11 - 1 = 10)
- I has positional value 9 (10 - 1 = 9)
Following the pattern of decreasing by 1, the next letter is 9 - 1 = 8, which corresponds to H.

3. Third letter pattern:
P → O → N → M → ?
- P has positional value 16
- O has positional value 15 (16 - 1 = 15)
- N has positional value 14 (15 - 1 = 14)
- M has positional value 13 (14 - 1 = 13)
Following the pattern of decreasing by 1, the next letter is 13 - 1 = 12, which corresponds to L.

Combining the results for each position (P, H, L), the term that replaces the question mark is PHL.
